Thanks for the suggestion, I was able to make the necessary changes and pass the configure and make process. Unfortunately, after uploading and running the app, the app will not run: # ls -al /tmp -rwxrwxrwx 1 root root 2434012 Aug 12 01:44 stunnel -rw-r--r-- 1 root root 1148 Aug 12 01:37 stunnel.conf -rw-r--r-- 1 root root 1977 Aug 12 01:44 stunnel.pem drwxr-xr-x 1 root root 0 Dec 31 1969 var # cd /tmp # ./stunnel -sh: ./stunnel: not found The file is obviously there, with execute permissions. What is failing?? Thank you > checking for "/dev/ptmx"... configure: error: cannot check for file > existence when cross compiling. > > Give me your suggestions. Check that /dev/ptmx exists on your router; it does on my Buffalo router with Tomato. If it does, then hack the configure script to force the test to return true. A search in the script for ptmx should take you right to the test. Good luck, Andrew. -- Be Yourself @ mail.com! Choose From 200+ Email Addresses Get a Free Account at www.mail.com!

Stunnel configure error

I have been receiving errors when configuring Stunnel, which I intend to cross compile for use with my Linksys WRT54GL router (Tomato firmware). When passing ./configure --host=mipsel-linux --with-ssl=/root/openssl --enable-static --enable-dh --libexecdir=/tmp the configure process stops with an error. Here is the complete output. ./configure --host=mipsel-linux --with-ssl=/root/openssl --enable-static --enable-dh --libexecdir=/tmp configure: WARNING: If you wanted to set the --build type, don't use --host.

stunnel, haproxy and ssl cert
by Maxim 04 Aug '09

04 Aug '09

Hello dear community. I faced some troubles for iphone: I moved separate server from hardware to AWS Cloud with SSL certificate from Register.com. It moved well, and phone application continue work with new server without any problems. Then I installed LoadBalancer (HAProxy and Stunnel) for it and moved certificate with key from configs of Apache to config of stunnel. In PC browser it continue works well, and shows me blue field near the URL as trusted. But on iPhone browser it shows just "Untrusted server certificate". Is there any difference for ssl certificate for stunnel and Apache? I understand that there is very specific question, but would you have any ideas about it? *Config of stunnel:* cert = /usr/local/etc/stunnel/stunnel.pem chroot = /usr/local/var/lib/stunnel/ setuid = nobody setgid = nobody pid = /stunnel.pid socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1 debug = 7 output = stunnel.log [https] accept = 443 connect = 80 xforwardedfor=yes TIMEOUTclose = 0 *Patch for stunnel* http://haproxy.1wt.eu/download/patches/stunnel-4.22-xforwarded-for.diff need to make work "xforwardedfor=yes" *# stunnel -version* stunnel 4.22 on i686-pc-linux-gnu with OpenSSL 0.9.8b 04 May 2006 Threading:PTHREAD SSL:ENGINE Sockets:POLL,IPv6 Auth:LIBWRAP Global options debug = 5 pid = /usr/local/var/run/stunnel/stunnel.pid RNDbytes = 64 RNDfile = /dev/urandom RNDoverwrite = yes Service-level options cert = /usr/local/etc/stunnel/stunnel.pem ciphers = AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH key = /usr/local/etc/stunnel/stunnel.pem session = 300 seconds stack = 65536 bytes sslVersion = SSLv3 for client, all for server TIMEOUTbusy = 300 seconds TIMEOUTclose = 60 seconds TIMEOUTconnect = 10 seconds TIMEOUTidle = 43200 seconds verify = none * # uname -a* Linux domU-12-31-38-00-35-07 2.6.18-xenU-ec2-v1.0 #2 SMP Tue Feb 19 10:51:53 EST 2008 i686 athlon i386 GNU/Linux * # openssl version* OpenSSL 0.9.8b 04 May 2006 *And logs from stunnel when iphone tryed to conenct* 2009.08.04 08:20:16 LOG7[31023:3081598672]: https accepted FD=15 from 24.5.77.143:58019 2009.08.04 08:20:16 LOG7[31023:3081550736]: https started 2009.08.04 08:20:16 LOG7[31023:3081550736]: FD 15 in non-blocking mode 2009.08.04 08:20:16 LOG7[31023:3081550736]: TCP_NODELAY option set on local socket 2009.08.04 08:20:16 LOG7[31023:3081550736]: Waiting for a libwrap process 2009.08.04 08:20:16 LOG7[31023:3081550736]: Acquired libwrap process #0 2009.08.04 08:20:16 LOG7[31023:3081550736]: Releasing libwrap process #0 2009.08.04 08:20:16 LOG7[31023:3081550736]: Released libwrap process #0 2009.08.04 08:20:16 LOG7[31023:3081550736]: https permitted by libwrap from 24.5.77.143:58019 2009.08.04 08:20:16 LOG5[31023:3081550736]: https accepted connection from 24.5.77.143:58019 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): before/accept initialization 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 read client hello A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 write server hello A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 write certificate A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 write server done A 2009.08.04 08:20:16 LOG7[31023:3081550736]: SSL state (accept): SSLv3 flush data 2009.08.04 08:20:16 LOG3[31023:3081550736]: SSL_accept: Peer suddenly disconnected 2009.08.04 08:20:16 LOG5[31023:3081550736]: Connection reset: 0 bytes sent to SSL, 0 bytes sent to socket 2009.08.04 08:20:16 LOG7[31023:3081550736]: https finished (0 left) Thank you in advance, Max

[patch] Redirect to a fake destination if client's certificate couldn't be verified
by Jeremie Le Hen 29 Jul '09

29 Jul '09

Hi list, I've written a patch to bring in the following directives: - evilconnect - evilexec/evilexecargs The idea is when stunnel works in server mode and is asked to verify the client's certificate, it normally shuts the connection down when the latter is invalid. With these options, when the certificate can't be verified, stunnel redirects the "evil" connection to another destination. What is the purpose of this new feature ? For instance, if your company does not allow SSH connections out, you may use the following configuation: % connect = yourdomain.com:22 % evilconnect = www.yourdomain.com:80 So you will access your SSH server with your valid user certificate. On the other hand, if an over-zealous sneaky admin looks at the proxy logs and tries to connect to your stunnel, it will be redirected to an uninteresting website ;). Here is the documentation: % evilconnect = [host:]port % connect to a remote host:port when the client's certificate cannot % be verified % % This is only meaningful in server mode when connect and verify are % used. Otherwise it has the same properties as the connect option. % % evilexec = executable_path (Unix only) % execute local inetd-type program when the client's certificate can- % not be verified % % This is only meaningful in server mode when exec and verify are % used. Otherwise it has the same properties as the exec option. % % execargs = $0 $1 $2 ... (Unix only) % arguments for evilexec including program name ($0) % % Quoting is currently not supported. Arguments are separated with % arbitrary number of whitespaces. I'd like to thank Mathieu CHOUQUET-STRINGER who actually had this very good idea and implemented a proof of concept code with GnuTLS. Also, thank to Vin0x64 <vincent vin0x64 fr> who tested this patch and verified that it works. Looking forward for your remarks... thanks! Best regards, -- Jeremie Le Hen < jeremie at le-hen dot org >< ttz at chchile dot org >

Stunnel listen on different ports
by Noel Sanchez 21 Jul '09

21 Jul '09

I have had a working stunnel conf for much time, very happy with it. [stunnel] accept = 0.0.0.0:30000 connect = 192.168.27.102:8000 I have stunnel listening on port 30000 and then sending to 192.168.27.102 on port 8000. Works good. I now want to add more listening ports to stunnel, like so: [stunnel] accept = 0.0.0.0:30000 connect = 192.168.27.102:8000 accept = 0.0.0.0:30006 connect = 192.168.27.102:8006 When I do this, stunnel only binds to 30006, per my log file: stunnel bound to 0.0.0.0:30006 And when I do a netstat -vatn: tcp 0 0 0.0.0.0:30006 0.0.0.0:* LISTEN It is not listening on port 30000 anymore. I'd like to accepts connections on many different ports, then send accordingly. Can I do this? Why does stunnel only listen to one port when I add more accept lines in its config? Noel

Re: [stunnel-users] using webdav: YES IT WORKS WITH NET USE

Well after some more tests I achieve net use to work: UseBasicAuth is VITAL on the xp client (reboot) Accordingly configure apache with basic plain text auth stunnel routing localhost:80 to remote:443 (as you did) to pass your credentials use EXACTLY this command line : net use y: \\localhost\davfolder (with no extra \) YOURPASSWORD /USER:YOURUSERNAME (this in the only way to have hhtp credentials sent to the server). tested on client: xpsp2 + kb892211 + kb911927 (IMPORTANT ALSO, needs reboot) + stunnel 427 and server apache 2.2.6/Mandriva 2008. kb907306 replaces 892211, but I have not tested with it (I think it should work).

Common Name checking
by Mark Bolton 15 Jul '09

15 Jul '09

Hi, I believe this has been discussed before on the list but I wanted to get a better understanding and confirm the current situation. Is it still correct that when using verify=2, the peer's hostname is not checked (via a name service lookup) to match the Common Name in the presented certificate? With the main reason being that you cannot necessarily trust the name service? I am asking because we have a closed network in which we do trust our dns servers, and Common Name checking would be advantageous to us given the following scenario: We have is that a single (central) host that connects to multiple 'client' hosts via stunnel. The central host presents a certificate signed by our own CA. Each client has a copy of our CA's certificate and has verify=2. So when the central server connects, the client checks that the certificate presented has really been signed by our own CA. So using this mechanism, only servers (i.e. the central server) with a signed certificate are allowed to connect. All good so far, however the problem is if the signed certificate is copied (stolen) to another server. This 'other' server can connect to all the clients also. With Common Name checking, the clients could as well as checking the signature, check the presenting host has the same hostname as in the certificate. Is there anyway we can use stunnel to help us guard against this 'stolen cert' situation or if not what else could we do? Thanks, Mark
